The new line of Accuton is a true breakthrough in high technology applied
to speakers. For the first time ever you can build an all ceramic system, from tweeter to woofers! All Accuton
diaphragms are made of pure Al203 in the alpha crystal lattice (corrundum) through a unique process. This ultra
hard material provides high internal sound velocity and pure piston behavior, which translate into very low distortion
and virtually no coloration. For specs check out the Accuton Home page.

D20-6-31 Pure Diamond 3/4" Dome Tweeter

Yes a pure Diamond Driver! The new D 20-6 has a membrane made of a single
piece of pure diamond. It goes from 2 kHz to almost 100 kHz and shows harmonic distortion magnitudes lower than
conventional tweeters. The stiffness to weight ratio of the membrane is about five times higher than even the extremely
rigid ceramic drivers. The sound propagation in the diamond material is almost 18,000 m/sec, the highest in any
existing material. The D20-6 is manufactured to the exact specifications of the C12 (see below). It may be used
as an upgrade to existing loudspeaker boxes using the C12. Frequency range is extended to almost 100 kHz. Ferrofluid
loaded for increased power handling. Distortion figures are magnitudes below usual tweeters, even well below the
respected C12 which many people already consider to be the best tweeter of the high-end world.

C25-6-12 Ceramic 1" Dome Tweeter

1" super tweeter. Featuring usable response out to 30 kHz, this unit
still has a remarkably low 700 Hz Fs and exceptionally flat response down to 2 kHz. Cone breakup occurs well over
20 kHz. With its 100 W filtered power rating, this is one of the few super tweeters which can be used in a 2-way
system.

C30-6-23 Ceramic 1.2" Dome Tweeter

High efficiency, ferrofluid filled tweeter with 1.2" lightweight concave
ceramic dome. Usable in 2-way systems or high power 3-way designs. Very high resolution and very good dispersion
up to 23 kHz. Low resonance frequency allows first or second order filtering and a crossover frequency as low as
1.4 kHz. Featuring response similar to the C12 in the audible range the C23 adds the virtues of even greater power
handling and an incredibly low (for a tweeter) Fs of 350 Hz! Many consider this unit to be the ultimate electrodynamic
tweeter.
